Malcesine's most prominent landmark is the Castello Scaligero, which has 13th-century fortifications and an older medieval tower in white natural stone. Like the castle of Sirmione at the southern end of the lake, it is named for the della Scala family of Verona who ruled the region in the 13th and 14th centuries, and has the characteristic swallow-tail Ghibelline merlon crenallations. Remnants of an Etruscan tomb have been found within the castle walls. Most of the structures visible today date to the period of the della Scala. The bell of the castle was cast in 1442 and it is still in service.
In September 1786, Johann Wolfgang Goethe was questioned by the local magistrate on suspicion of being an Austrian spy after drawing sketches of the castle, and recalled the incident in his published travel report Italienische Reise (Italian Journey). During the period of Austrian rule, which ended in 1866 after the Third Italian War of Independence, major renovation work took place inside the castle. The Austrians turned it into a military garrison and the munition store they constructed was later used by the Guardia di Finanza of the Kingdom of Italy as a prison. Since 1902, the castle has been a national monument.
Today, the castle contains a small museum on the natural history of Lake Garda and Monte Baldo. One room in the Austrian powder magazine is dedicated to Goethe and his visit.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
